Corneal surgery risk evaluation method and system thereof

Abstract

This invention provides a corneal surgery risk evaluation method and system thereof. Utilizing a mechanical numerical model to evaluate stress differences before corneal surgery and after, and further providing a suggested surgical path and risk after surgery. The evaluation method, comprising: measuring Intraocular pressure (IOP); inputting geometric parameters and material parameters of multi-layer of corneal; constructing a first corneal numerical model; constructing a second corneal numerical model with at least one cutting path character; evaluating whether the cutting path character should be re-constructed or not.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a mechanic evaluation method and system, especially a corneal surgery risk evaluation method and system thereof after calculating by a numerical model.2. Description of the Prior Art[0002]In general, the process of normal human eye to receive light source and generate an image is that the refractive light source by cornea passes through pupil, and then adjusting the intensity of the light source by pupil dilation or miosis actuated by iris. Then the light source refracts via lens and focuses on the retina to form the image. The image is transmitted to brain through optic nerve. In said process, the spherical curvature of cornea is very important. If the function is normal, the light source can be refracted correctly and focused clearly on the retina. If the surface of the retina is abnormal or the thickness is uneven, the image will not be focused on the retina so that a blurred vision will oc...

AI Technical Summary

Benefits of technology

The present invention is a better way to evaluate how well surgery has done. It uses a mechanical model to compare before and after surgery, and it can help to make the surgery safer and more accurate.

Problems solved by technology

If the surface of the retina is abnormal or the thickness is uneven, the image will not be focused on the retina so that a blurred vision will occur.

In addition to the above-mentioned problems, there are corneal lesions, ulcers or injury resulting in irregular corneal spherical curvature which leads to blurred vision.

However, before current surgical operation, there is no more accurate evaluating means for doctors to consult.

In the surgical procedure, there are also other factors (such as medicine physician wield special eye mechanical properties of the cornea is not completely grasp) may cause failures of surgery, ineffective operation, or mild impact causes rupture and sequela.

For those who need to surgery, it is insecure and uncertain.
